Discrete Math Question 22.3 and 22.4
22.3
If all the vertices of a graph G are of degree greater than five, then G is not simple or G is not planar or G is not connected.
22.4
All the vertices of the graph G in Figure 10 are of degree greater than five.
Then by the previous theorem
G is not simple or G is not planar or G is not connected
But G is simple and also connected, therefore G is not planar.
Question 22.3 (G3/P2) Write the contrapositive of the following Theorem: If G is simple, planar, ...
solve with steps 1. (20 points) True or false. Justify. Every planar graph is 4-colorable /2 The number of edges in a simple graph G is bounded by n(n 1) where n is the number of vertices. The number of edges of a simple connected graph G is at least n-1 where n is the number of vertices. Two graphs are isomorphic if they have the same number of vertices and 1) the same mumber of edges 1. (20 points)...
8. For each of the following, either draw a undirected graph satisfying the given criteria or explain why it cannot be done. Your graphs should be simple, i.e. not having any multiple edges (more than one edge between the same pair of vertices) or self-loops (edges with both ends at the same vertex). [10 points] a. A graph with 3 connected components, 11 vertices, and 10 edges. b. A graph with 4 connected components, 10 vertices, and 30 edges. c....
